c# - WebAPI One Asp.Net (ASP5/vNext) 中的分页

Question

我正在尝试使用 ASP 5.0 WebAPI 在客户 Controller 中进行分页。当我尝试做这个例子时，我得到:

Cannot implicitly convert type Microsoft.AspNet.Mvc.HttpOkObjectResult to API.Controllers.IHttpActionResult

我只需要返回一个包含当前页数、总页数和结果的客户集合。

public IHttpActionResult Get(int offset = 0, int limit = 50)
{
    // Get total number of records
    int total = _dbContext.Customers.Count();

    // Select the customers based on paging parameters
    var customers = _dbContext.Customers
        .OrderBy(c => c.Id)
        .Skip(offset)
        .Take(limit)
        .ToList();

    // Return the list of customers
    return Ok(new
    {
        Data = customers,
        Paging = new
        {
            Total = total,
            Limit = limit,
            Offset = offset,
            Returned = customers.Count
        }
    });
}

您需要将IHttpActionResult 更改为IActionResult

Controller.Ok() 返回 HttpOkObjectResult ...

public class HttpOkObjectResult : ObjectResult, IActionResult {...}

...而您的方法签名定义了 IHttpActionResult，它来自以前的版本
